Each complex 16number consist of two parts called In-phase and Quadrature (IQ). Both I 17and Q are represented as a 16 bit unsigned big endian number stored in 1832 bit space. The remaining unused bits within the 32 bit space will be 19padded with 0. I value starts first and Q value starts at an offset 20equalling half of the buffer size (i.e.) offset = buffersize/2. Out of 21the 16 bits, bit 15:2 (14 bit) is data and bit 1:0 (2 bit) can be any 22value. 23 24**Byte Order.** 25Each cell is one byte. 26 27.. flat-table:: 28 :header-rows: 1 29 :stub-columns: 0 30 31 * - Offset: 32 - Byte B0 33 - Byte B1 34 - Byte B2 35 - Byte B3 36 * - start + 0: 37 - I'\ :sub:`0[13:6]` 38 - I'\ :sub:`0[5:0]; B1[1:0]=pad` 39 - pad 40 - pad 41 * - start + 4: 42 - I'\ :sub:`1[13:6]` 43 - I'\ :sub:`1[5:0]; B1[1:0]=pad` 44 - pad 45 - pad 46 * - ... 47 * - start + offset: 48 - Q'\ :sub:`0[13:6]` 49 - Q'\ :sub:`0[5:0]; B1[1:0]=pad` 50 - pad 51 - pad 52 * - start + offset + 4: 53 - Q'\ :sub:`1[13:6]` 54 - Q'\ :sub:`1[5:0]; B1[1:0]=pad` 55 - pad 56 - pad 57
